A Novel Identity Based Undeniable Signature Scheme

摘要：

In this paper, we give a first example of identity based undeniable signature from NTRU lattice. We extend to the identity based setting the security model for the notions of invisibility and anonymity given by Galbraith and Mao in 2003 and we prove that our scheme is existentially unforgeable under the assumption in the random oracle model. We also prove that it has the unfogreability and anonymity property under our scheme.
